Specification of Letters Patent.

Patented June 2, 1914.

To all whom it may concern Be it known that I, 'WLAnYsLAw CZA R- nnonr, a subject of the Emperor of Russia,

residing in Philadelphia, Pennsylvania, have vide a relatively simple, eflicient and subportion 3 proj ectin stantial nozzle for delivering liquid in the form of a spray, whose parts shall of such designas to permit of their oonvenlent examination, the device as a whole being of such a nature as to not be liable to get out .of order or require repair.

These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which v Figure 1 is a side elevation of a nozzle structure constructed according to my invention; Fig.2 is an elevation partlyin section, further illustrating the device shown in Fig. 1; Fig. 3 is a plan of the body of the nozzle; Fig. 4- is an enlarged firagmentary section illustrating the detail construction of the nozzle body.

In the above drawings, 1 represents the body of the muscle which consists of a hollow base 2- having the general form of a nut and in addition provided with a hollow threaded from one of its faces. This threaded portion terminates in a relatively narrow cylindrical part 4 surmounted by a conical end 5 andthere are a series of holes or passages 6 leadingfrom the hollow interior of the body so as to open on the cylindrical surface of the part 4. passages are straight and extend upwardly and outwardly, their lines being alltangent to a circle concentric with the axis of'the nozzle structure, and all inclined in the same being surmounted by a delivery end 9. This latter is hollow, being internally threaded in order to fit upon the threaded part 3 of the body, and having an internal generally conical chamber 10 with uninterrupted uniformly inclined walls inclosing the cylindrical part, 4, of the body, said chamber, 10, .being of such proportions that when the parts are assembled as shown in Fig. 2,-its conical walls are spaced away from the cylindrical portion 4 and the conical portion 5 of the body. This hollow chamber terminatesin a relatively narrow cylindrical outlet passage 11 whose outer end enters a divergent outlet passage 12.

With such an arrangement and construc-' tion of parts, liquid flowing under pressure through the interior of the body 1 is de livered in a series of outwardly and upwardly inclined lines, all inclined. in the same direction around the axis'of the noz-i zle. As a consequence, when the liquid enters the part of the chamber 10 formed by the portions 4 and 5 of the body and the head 7, it has a divergent rotary movement which to some extent very effectually breaks it up into relatively fine drops or particles. It is then discharged through the passage '11 and the divergent opening 12, so that it is delivered in the form of a more or less solid cone or spray whose apex is substantially coincident with the outer end of the passage 11. Owing to the inclination of the passages, 6, the particles of llquid in this conical body or sheet of spray have a more or less rotary movement, so that when the app'aratus is used as a burner, the particles of liquid fuel delivered are of such fineness as tobe efficiently and rapidly burned, it being noted that the process of, combustion is greatly aided by the intimate mixture of air and liquid particles, resulting from the rotary and divergent paths given the particles of such liquid as these leave the nozzle. When liquid under pressure is delivered from these openings, it strikes the adjacent uniformly inclined walls of the chamber 14 The combination in a nozzle of a tubular body having a nut-formed portion constitoting a shouldered-base, and a threaded part terminating in a cylindrical I portion surmounted by a conical extremity there be from its threaded part atan'angle different ing upwardly and outwardly inclined pasfrom that of the conical end of the body, sages from the interior of the body opening and having an outlet passage at its apex.

on the cylindrical portion thereof, With a In testimony whereof, I have signed my 15 head also having a nut-shaped base and inname to this speeification, in the presence of teriorly threaded to fit on the threaded two subscribing witnesses.
